Struct wasmtime_environ::__core::slice::GetManyMutError

pub struct GetManyMutError<const N: usize> { /* private fields */ }

🔬This is a nightly-only experimental API. (get_many_mut)

The error type returned by get_many_mut<N>.

It indicates one of two possible errors:

• An index is out-of-bounds.
• The same index appeared multiple times in the array.

Examples

#![feature(get_many_mut)]

let v = &mut [1, 2, 3];
assert!(v.get_many_mut([0, 999]).is_err());
assert!(v.get_many_mut([1, 1]).is_err());

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
